FLUKE 1738 Advanced Power and Energy Logger

Get more visibility, reduce uncertainty and make better power quality and energy consumption decisions.

The FLUKE 1738 Three-Phase Advanced Power and Energy Logger built with FLUKE Connect mobile app and desktop software compatibility is the ideal tool for conducting energy studies and power quality surveys.

  • Automatically capture and log voltage, current, power, harmonics and associated power quality values
  • Capture dips, swells and inrush currents: includes an event waveform snapshot and a high-resolution RMS profile, to give your electrical system a power quality health check and discover where and when energy is being wasted
  • Conveniently power the instrument directly from the measured circuit


FLUKE 1738 Key Features:

Key measurements: Automatically capture and log voltage, current, power, harmonics and associated power quality values, and capture dips, swells, and inrush currents with event waveform snapshots and high-resolution RMS profiles
Convenient instrument powering: 
Power instrument directly from the measured circuit
Energy Analyse Plus application software: 
Download and analyse every detail of energy consumption and power quality state of health with our automated reporting and use the integrated power quality health summary to get an at-a-glance understanding of system health

  • Present data locally on the logger, on the FLUKE Connect mobile app and desktop software, or through your facility’s Wi-Fi infrastructure
  • Measure all three-phases and neutral with four flexible current probes (included)
  • Power the instrument directly from the measured circuit
  • Review measured values during logging sessions and before downloading for real-time analysis
  • Includes event waveform snapshot and high-resolution RMS profile with the 1738, along with date, timestamp and severity to capture dips, swells, and inrush currents and help pinpoint potential root causes of power quality issues 1738 also provides fast insight into overall electrical system health with a
  • Power Quality Health Summary
  • Offers a bright, colour touch-screen display for convenient field analysis and data checks
  • Helps you capture the right data every time with a quick, guided, graphical user interface
  • Reduces uncertainty about your connections with the intelligent verification function
  • Allows you to complete field setups through the front panel or the Fluke Connect App on your smartphone
  • Provides fully integrated logging with other FLUKE Connect enabled devices to simultaneously log up to two additional measurement parameters on a Fluke Connect wireless digital multimeter or module*


What Extra Advance Features Do I Get With The FLUKE 1738?

(Compared to the FLUKE 1736)

Recording capability:

  • Inrush

When a large load energises, it is common to have a large increase of current for a short period of time, typically referred to as inrush current. Often there is a decrease in voltage at the same time referred to as a dip. 

  • Event Waveform Capture

Equipment trips or resets can often be triggered by a significant decrease in the voltage. Depending on the sensitivity of the equipment, this could be as fast as a portion of a waveform or something that lasted many cycles showing up in the RMS trend data. 

  • Power Quality Health (EN50160 analysis) comes as standard with the 1738
  • IEEE 519 reporting comes as standard with the 1738

Enables validation of voltage and current harmonics according to the standard IEEE 519, and the PQ study can be switched to view the pass/fail bar graph as IEEE 519 values. Allows creation of IEEE 519 Reports giving you more insight into harmonic levels, voltage, and current distortion, and load current.
